Module 9: Volume Interpretation and Advanced Visualization

Module 9 facilitates advanced volume-based seismic interpretation, allowing for seamless integration with 2-D seismic workflows. It enables the tracking and editing of horizons within 3-D seismic attribute volumes, fault interpretation with real-time construction of fault surfaces, and geobody interpretation using multiple algorithms. This module also offers sophisticated volume visualization techniques, including co-rendering and multi-attribute overlay, color blending for enhanced data interpretation, and the creation of rose diagram and vector plots for detailed analysis of seismic attributes.

Key Features

  1. Horizon Interpretation:
    • Track single or multiple horizons across one or more seismic attribute volumes in 3-D based on waveform analysis.
    • Perform real-time editing of horizon surfaces in 3-D to eliminate abnormal traces.
    • Utilize horizon editing capabilities through 2-D cross plotting for enhanced precision.
  2. Fault Interpretation:
    • Digitize fault sticks directly on seismic sections or time slices in 3-D, with fault surfaces automatically constructed in real-time during the digitization process.
    • Employ seed point selection on fault likelihood attributes to track fault surfaces efficiently.
    • Automatically generate fault surfaces from fault likelihood attribute volumes with customizable parameter controls.
  3. Geobody Interpretation:
    • Create geobodies using various algorithms.
    • Apply paint brushing techniques on sections, horizons, and time slices with adjustable threshold values.
    • Perform thresholding based on single or multiple attributes, including conversion from facies volumes or facies strata-grids.
  4. Volume Visualization:
    • Adjust volume opacity for sub-volumes within multiple 3-D attribute volumes, horizons, and strata-grid attributes.
    • Employ physically based volume rendering techniques for visualizing multiple attribute volumes effectively.
  5. Co-rendering & Multi-attribute Overlay:
    • Define co-rendering objects by selecting any two attributes for visualization in 2-D and 3-D windows, with customizable color map and opacity curve adjustments.
    • Overlay an unlimited number of attributes on the same seismic section and base map windows for comprehensive analysis.
  6. Color Blending:
    • Define RGB(A) objects by selecting three or four attributes for rendering in 2-D and 3-D visualization windows.
    • Automatically create RGB volumes after spectral decomposition calculation, with non-linear data-color transform options to highlight specific ranges of interest.
  7. Rose Diagram Plot:
    • Define the size of a rectangular area to visualize rose diagrams of azimuthal attributes in 3-D and 2-D windows, providing insights into directional attributes.
  8. Vector Plot:
    • Define vector plot objects by specifying attributes representing length, orientation, dip, and color of a rectangular area.
    • Utilize vector plots for visualizing pre-stack inversion attributes such as fracture density and orientation volumes, facilitating detailed analysis.
